Strategy Blog
Investors, traders, fund managers, and market pioneers whose methods shaped how markets are studied.
Each profile digs into how a great market thinker made decisions: what they watched, what they avoided, and which lessons still help a retail investor read businesses, prices, risk, and crowd behavior with more judgment.
Robert D. Arnott · Fundamental index investing
Rob Arnott turned a technical argument about index weighting into a durable investing business, but his career is also a warning about backtests, crowded factors, and the patience required when contrarian rules underperform.
Economist-investor · Concentrated contrarian value investing
The economist who changed macroeconomics also changed institutional investing by turning King's College, Cambridge toward equities, concentration, value, and the uncomfortable discipline of being early.
Finance scholar · Behavioral valuation and bubble analysis
The Nobel-winning Yale economist changed how investors think about valuation, housing prices and speculative manias by insisting that markets are driven by data, institutions and contagious stories.
Technology investor · Data-driven technology growth investing
Mary Meeker’s career traces the migration of technology investing from Wall Street research to Silicon Valley growth capital, with a method built on data density, product intuition, and a persistent willingness to back digital adoption before it looks obvious.
Financier · Patient contrarian speculation
Bernard Baruch made a fortune as an independent speculator, then carried Wall Street's habits of fact gathering, cash discipline and wartime organization into the center of American public policy.
Mutual fund manager · Low-priced small-cap value investing
Joel Tillinghast turned an awkward-sounding Fidelity mandate into a three-decade argument for disciplined stock picking, but his record also shows how scale, value traps and changing markets test even the most patient investor.
Trading pioneer · Systematic futures trend following
Richard Donchian built the first publicly managed futures fund, codified rules for following price trends, and gave later systematic traders a durable but unforgiving language for risk.
Market pioneer · Dow Theory trend confirmation
Charles Dow began as a reporter trying to make Wall Street legible, and his averages became a market language that still shapes how investors think about trends, confirmation, risk, and the limits of prediction.
Value investor · Dhandho value investing
The founder of Pabrai Investment Funds built a career on Buffett-style value investing, Dhandho odds, concentrated bets, and radical borrowing of good ideas, but his record also shows how hard it is to hold compounders and survive the air pockets that come.
Growth investor · Long-term growth investing
Ron Baron made Baron Capital a rare active-growth survivor by owning exceptional businesses for years, but the same patience that powered Tesla and SpaceX has also created one of modern fund management's sharpest concentration debates.
Value investor · Activist value investing
Michael Price turned the quiet craft of buying discounted assets into a public contest for corporate control, proving that a mutual fund manager could force change long before activism became a crowded hedge fund trade.
Trader · Disciplined short-term momentum trading
The trader known as Pit Bull turned a bruising decade of losses into one of Wall Street's most studied short-term trading careers, but his story is as much about ego, stress and survivorship as it is about market timing.
Quantitative investor · Quantitative factor investing
The AQR co-founder turned academic asset pricing into institutional portfolios built on value, momentum, quality, and discipline, then faced the hardest test of any quant strategy: surviving when the evidence stopped working on schedule.
